An international research team has tested a hybrid control technique combining adapted perturb and observe (APO) with model-predictive control to address complex partial shading in solar arrays. The ...

Electronic ballasts for fluorescent lighting deliver high efficiency and long lamp lifetimes. A new and simplified control circuit demonstrates complete control of the ballast, including all necessary ...

Modern electronic systems need small, lightweight, high-efficiency power supplies. These supplies require cost-effective methods to take power from the AC power distribution grid and convert it to a ...

The need for cost-effective solutions to improve power factor correction (PFC) at light loads and with peak efficiency while shrinking passive components is becoming difficult with conventional ...
